Answer:
The answer is
<h3>1.340 × 10²⁴ sodium atoms</h3>
To find the number of atoms of sodium we use the formula
N = n × L
where
n is the number of moles
N is the number of entities
L is Avogadro's constant which is
We need to find the number of moles first
The formula is
where
M is the molar mass
m is the mass
n is the number of moles
From the question
M = 22.9 g/mol
m = 51.0 g
n = 2.227 moles
So the number of sodium atoms is
We have the final answer as
<h3>1.340 × 10²⁴ sodium atoms</h3>
